Patent JP-H022613-A (JP)
Title: Manufacture of semiconductor
Inventor: AMIKURA MANABU
IPC: H01L21/265
Filed: 1988-06-16
Abstract: PURPOSE:To remarkably decrease dusts stuck to a processed substance without rapidly decreasing the throughput for enabling successful processing by evacuating an air from a case at first comparatively slowly and then quickly to the vacuum specified beforehand. CONSTITUTION:To perform a specific processing by loading a case 2 with a semiconductor wafer, an air is evacuated from the case 2 at first comparatively slowly and then quickly to the vacuum specified beforehand. For example, after loading a loadlock chamber 2 with a semiconductor wafer, an air is evacuated from the chamber 2 at first slowly with a bypass piping 6 for several seconds, and then quickly with an exhaust piping 4 for several seconds until the pressure in the loadlock chamber 2 becomes the specified value by switching over solenoid valves 5 and 7 with a controller 12. And then the semiconductor wafer is moved on to the platen in a vacuum chamber 1 with a carrier arm etc., with a switching mechanism between the vacuum chamber 1 and the loadlock chamber 2 open and an ion is implanted by scanning and applying an ion beam.

Title: Disk device and zone discriminating method of disk
Inventor: MINODA HIROSHI
IPC: G11B19/02
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce latter processing time corresponding to the amount of time required to obtain a PID information by discriminating the zone, in which irradiating light beams are positioned based on the signals obtained from a disk, without reading the physical addresses on the disk having plural zones. SOLUTION: While a disk is rotated, a zone in which irradiated light beams are located, is discriminated. If the zone is not located in a target zone, it is returned to a seek processing and an objective lens is moved so that the target zone is irradiated with the beam again. If the irradiated light beams are located in the target zone, the setting of a disk rotation is a waited, a timer start is conducted to monitor the time out of the PID information acquisition and a PID fetch is conducted. Since whether the objective lens is located at an objective zone or not is decided prior to the setting of a disk rotational speed during a seek, a zone discrimination is made prior to the acquisition processing of the PID information, the moving time to a next seek is reduced when the lens is not located at an objective zone.

Title: Microwave plasma generating device
Inventor: ITO TATSUO
IPC: H01L21/3065
Filed: 1986-06-25
Abstract: PURPOSE:To minimize the loss in microwave supply power consumption by a method wherein an even number exceeding at least two each of passive reflectors are provided in waveguides almost in parallel with each other at an interval equivalent to 1/4 of the wavelength in the microwave guide. CONSTITUTION:An even number exceeding at least two each of passive reflectors 6a, 6b reflecting microwaves are provided in waveguides 7, 13 opposing to a discharge region 14 while the passive reflectors 6a, 6h are almost in parallel with each other at an interval equivalent to 1/4 of the wavelength in the microwave guide. At this time, considering the microwaves proceeding in the incident direction out of the waves reflected by the passive reflectors 6a, 6b, the path difference between the reflected waves due to the first passive reflector 6a and the one due to the second passive reflector 6b is 1/2 of the guide wavelength while a return trip is made, and consequently is Shifted by 180 degrees making the reflected waves cancel each other. Resultantly, the returning waves in the incident direction are reduced to minimize the loss in power consumption. Furthermore, the microwaves are irregularly reflected to expand the plasma producing space.

Title: Analog adder
Inventor: HOTTA MASAO

Filed: 1984-07-20
Abstract: PURPOSE:To make an adder act at a high speed without requiring PNP type transistor and to prevent the signal delay by connecting two or more analog input currents to the emitter of a transistor and simultaneously adding a level shift circuit. CONSTITUTION:The output of a D/A converter 2 is connected to one input terminal of an adder, while an analog input ei which should obtain a difference at the other input terminal 5 is connected to the emitter of a transistor Tr8, and the addition is executed. For a bias circuit, a constant current source 10 and diode 9 are connected to the base of the transistor Tr8 to form a base grounding-type amplifier. The added result is fetched from a collector of the Tr8 and a power source voltage is set at a high level to prevent saturating of the Tr8 in consideration of a voltage drop component to be produced at a resistance 14. Thus, since a DC off-set voltage is generated except an amplified signal voltage, a level shift circuit for consisting of a resistance 20, a capacitor 36 and a constant current source 21 is connected through a buffer amplifier 35. As a result, a high speed action can be accomplished without using a PNP type transistor and the signal delay can be prevented.
